Adequate illumination on the work surface is essential for cable terminations because technicians must clearly see tiny details—conductor insulation, wire strands, color coding, labels, and the exact alignment of connectors. When light is too dim, there’s a higher risk of mis-termination, misread labels, or subtle mistakes that can cause faults or future maintenance headaches, and it also strains the eyes over long tasks.

The minimum recommended level to support this careful work is 500 lux. This level provides enough brightness to reveal fine details and contrast without the glare that can come from attempting to work in overly bright conditions. If lighting drops to about 300 lux, shadows and low visibility can hide small features, increasing error risk. Levels well above 500 lux, such as 750 or 1000 lux, tend to be more than necessary for routine terminations and can add cost and potential glare, though they might be used for specialized inspection tasks.

So, 500 lux strikes a practical balance, enabling accurate terminations and comfortable, efficient work.
